We address in this paper automatic face verification from 3D (3-dimensional) facial surface and grey level analysis. 3D acquisition is performed by a structured light system, adapted to face capture and allowing grey level acquisition in alignment. The 3D facial shapes are compared and the residual error after 3D matching is used as a first similarity measure. A second similarity measure is der...

If an organisation is to achieve its goals in the current “Information Age”, the work of managers must be supported by high quality information. Systems that process organisational performance data into managerial information commonly have either dimensional or relational data structures. This paper reports the findings of a study of information support for university research managers and desc...

this paper addresses the validity of two hypotheses concerning changes of vowel quality in persian. the theory of centralization claims that there is a strong correlation between vowel duration and vowel quality. as vowel duration is shortened in unstressed contexts, the size of the vowel inventory reduces toward the center, leading to considerable overlap between different categories and a red...

The Coordinate Rotation DIgital Computer (CORDIC) algorithm has been used for many years for efficient implementation of vector rotation operations in hardware. It is executed merely by table look-up, shift, and addition operations. Thus, the corresponding hardware can be implemented in very economic fashion. Subsequently, it has been applied for many performances.CORDIC has been implemented in...

in this paper, two-dimensional heat transfer in a semi-infinite wall with fins of rectangular profile has been investigated. the conduction equations of the wall and fins are solved simultaneously by a numerical method. the principal parameters of the problem are the fin spacing, length, and fin-to-wall conductivity ratio. in this investigation, the effect of these parameters on two-dimensional...

This work is concerned with a direct sampling method (DSM) for inverse acoustic scattering problems using far-field data. Using one or few incident waves, the DSM provides quite reasonable profiles of scatterers in timeharmonic inverse acoustic scattering without a priori knowledge of either the physical properties or the number of disconnected components of the scatterer. We shall first presen...

background: standard cares in substance abuse treatment centers (satc) have an important role in treatment success achievement. patients’ views will provide valuable information to improve the performance of these centers. the purpose of current study was to determine patients’ comments on quality of addiction treatment at satcs. methods: this cross-sectional study was conducted in 2013. the st...
